After appointments to several posts as prefect, administrator and Registrar to the Imperial Chancellor, Jia Kui was enfeoffed as a Secondary Marquis for his work in keeping his jurisdictions prepared for battle and well-supplied.
Cao Xiu fell for a ruse by the Wu general Zhou Fang, who pretended to defect to the Wei side.
However, Jia Kui found Zhou Fang's defection suspicious and maintained his guard.
Although the Wu forces won the battle, Jia Kui managed to save Cao Xiu after his defeat and protect him while he retreated.
He continued serving as an official under the Jin dynasty after the end of the Three Kingdoms period, and was enfeoffed as a duke after his daughter Jia Nanfeng married the future Emperor Hui.
